Step 1 – Install HSPL2

http://xdaforums.com/showthread.php?t=611433

To check your HSPL version hold the volume down button...press the power button (red phone button at bottom left) till phone reboots.

·	You need HSPL2.08 or higher

If you have to downgrade your SPL version in order to get to HSPL2.08 have a look here http://xdaforums.com/showthread.php?t=898128 and at the bottom you will see a post explaining a bit more with this link to ROM's http://xdaforums.com/showthread.php?t=623283

Step 2 – Install Radio

http://xdaforums.com/showthread.php?t=611787

Make sure you read up on the radio's and that the radio you select will work on your phone. Example...don't use a USA radio (1024 ROM) for a 512 (ROM).

·	Get Radio (I used Leo_RADIO_2.14.50.02)

·	Reboot Phone – press volume down button to enter boot loader

·	Run CustomRUU (From Radio folder on PC)

·	Follow instructions on PC screen

·	You will notice on phone and PC that its installing

Step 3 – Install MagLDR

http://xdaforums.com/showthread.php?t=893618

·	You need MagLDR 1.12 or higher

·	Reboot Phone – press volume down button to enter boot loader

·	Run ROMUpdateUtility (From MagLDR folder on PC)

·	Follow instructions on PC screen

·	You will notice on phone and PC that its installing (It might wait a bit on 96% but don’t worry about that its normal)

·	Boot into MagLDR by holding power button down

Step 4 - Install WP7 ROM

I would recommend to install one of the ROM’s that has already unlocked your phone as it will ease your process. Choose a ROM from here: http://xdaforums.com/forumdisplay.php?f=977

You need installed MAGLDR 1.12 or higher (Done in Step 3)

·	Enter MAGLDR loader by pressing and holding the "Power button" if you aren’t already in it (End of Step 3).

·	Choose point 5 - "USB Flasher" then press Green button

·	Run DWI.exe (Vista/ W7 user should do that with administrator rights)

·	Done, you have WP7 ROM on your device

Step 5 – Install Zune

Step 6 – Install WP7 SDK

http://xdaforums.com/showthread.php?t=920275

For installing the WP7 SDK on XP Scroll down to Basingwas post…its the 5th one in that thread…it worked for me on XP.

Step 7 – Install XAP’s

Video

Watch this video if you are unsure what to do. Also the video doesn’t cover step 1 above which is needed. (HSPL2.08)

Additional Information

·	Not all SD cards work well with WP7 and if you run into weird problem it might be that your SD card is not fully compatible with WP7. Try replacing it and see if it helps. It might be useful to read the following thread:

Trouble Shooting

After step 3, my phone is stuck on HTC logo, I cannot go into MALGDR at all

·	Make sure that HSPL2.08 is flashed or HSPL3 with 2.08 flashed

·	Make sure you have the correct Radio installed by flashing the Radio again.

When Running DWI.exe it says error, USB Failed.
